DETAILED DESCRIPTION

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the present disclosure. However, it will be apparent to those skilled in the art that the embodiments, including structures, systems, and methods, may be practiced without these specific details. The description and representation herein are the common means used by those experienced or skilled in the art to most effectively convey the substance of their work to others skilled in the art. In other instances, well-known methods, procedures, and components have not been described in detail to avoid unnecessarily obscuring aspects of the disclosure.

References in the specification to “one embodiment,” “an embodiment,” “an example embodiment,” “some embodiments,” etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.

As used herein, the terms “upper” and “lower,” and “top” and “bottom,” and the like are intended to assist in understanding of embodiments of the invention with reference to the accompanying drawings with respect to the orientation of the beverage closure as shown, and are not intended to be limiting to the scope of the invention or to limit the invention scope to the embodiments depicted in the Figures. The directional terms are used for convenience of description and it is understood that a closure and a container may be positioned in any of various orientations.

The following examples are illustrative, but not limiting, of the present disclosure. Other suitable modifications and adaptations of the variety of conditions and parameters normally encountered in the field, and which would be apparent to those skilled in the art, are within the spirit and scope of the disclosure.

Many containers that include closures removably applied to a drinking opening for sealing the container involve removal of all or part of the closure to unseal the container and access the contents through the opening. For example, beverage containers often have a lid that must be unscrewed or otherwise removed from a drinking opening for a consumer to drink the beverage. Some beverage containers have so-called sports caps that do not require removal of the closure. These closures may twist to partially unscrew part of the cap or may slide up to expose a flow passage. However, these types of sports cap closures generally do not allow liquids to freely flow. Rather, liquid flow is induced by pressure (e.g., by squeezing the bottle or sucking on the cap at the outlet). Furthermore, removable caps may be readily lost or contaminated (e.g., when dropped on the floor or ground when separated from the container). And sports caps may not be easily separable to allow for cleaning within the cap.

The closures described herein provide the benefit of readily sealing and unsealing a drinking opening of a container (e.g., a beverage container) without requiring removal of components to unseal. Additionally, the closures described herein may be easily disassembled and reassembled, which allows a consumer to easily clean the components. All of this results in a closure that can be used and cleaned many times without being lost or broken. For example, to use the closure the user simply rotates a top portion of the closure, providing a user experience that is similar to traditional drinking closures that are removable from the container. Upon rotating the top portion, a central portion of the closure moves down to expose a fluid flow path. At that point, fluid in the container may flow freely through the drinking opening (e.g., by pouring). To reseal the closure, the user rotates the top portion in the opposite direction. This causes the central portion to move back up, creating a seal. The central portion can be removed from the closure to allow for convenient cleaning of the closure and container.

As shown throughout the figures, closure 100 may include base portion 200, central portion 300, and top portion 400. As discussed in more detail below, base portion 200 may be coupled to a container 600, as shown in FIGS. 1 and 2. Closure 100 may include drinking opening 410 that may be sealed when top portion 400 is in a first configuration (e.g., an open configuration, as shown in FIGS. 1, 3, and 5).

When base portion 200, central portion 300, and top portion 400 are assembled to form closure 100, drinking opening 410 may unsealed and resealed. Drinking opening 410 is sealed when top portion 400 is in a first configuration (e.g., a closed configuration). When top portion 400 is in the first configuration, central portion 300 is positioned to abut top portion 400, as shown in FIGS. 1 and 3. Top portion 400 may be rotated counter clockwise about central axis 411 from the first configuration to a second configuration (e.g., an open configuration). The second configuration may be any point between about 15 degrees from the first configuration to about 180 degrees from the first configuration.

As top portion 400 rotates, rotational engagement portion 330 (e.g., threads) may interact with engagement portion 420 (e.g., threads) such that central portion 300 moves down along central axis 411 (see, e.g., FIGS. 3, 4, and 7). Moving central portion 300 down along central axis 411 exposes a fluid flow path illustrated by arrows 700 (see FIG. 4) through the opening 230, fluid openings 340, and drinking opening 410.

In some embodiments, rotating top portion 400 at least 15 degrees from the first configuration exposes a fluid path sufficient for fluid to flow. In some embodiments, the fluid may flow through the fluid path when central portion 300 has moved down along central axis 411 by at least 2 millimeters. FIGS. 4 and 6 illustrate closure 100 when top portion 400 is in the second configuration and central portion 300 has moved down along central axis 411 to an open position. For example, in some embodiments the central portion moves at least 6 mm between the first configuration and the second configuration.

To reseal drinking opening 410, top portion 400 may be rotated clockwise about central axis 411 from the second configuration to the first configuration. As top portion 400 rotates clockwise, rotational engagement portion 330 (e.g., threads) may interact with engagement portion 420 (e.g., threads) such that central portion 300 moves up along central axis 411. When top portion 400 returns to the first configuration, central portion 300 abuts top portion 400 in a closed position to reseal drinking opening 410, which blocks flow path 700 (see FIG. 3). In some embodiments, as shown in FIG. 3, central portion 300 includes plug 310, top portion 400 includes flange 430, and plug 310 abuts flange 430 to form a seal.

In some embodiments, plug 310 may be formed of a resilient material, such that in the first configuration top portion 400 may press into and deform plug 310 to form the seal, as shown in FIG. 3. Upon movement into the second configuration, due to its resiliency plug 310 may return to its original form. Alternatively or additionally, the portion of top portion 400 that contacts plug 310 in the first configuration may be formed of a resilient material and may similarly deform in the first configuration to form the seal.

Closure 100 may be readily disassembled. Central portion 300 may be removably attached to base portion 200 and top portion 400. Central portion 300 may be separated from both base portion 200 and top portion 400 when top portion 400 is in the second potion (i.e., when drinking opening 410 is unsealed), as will be described in greater detail below.

Top portion 400 may be rotated relative to base portion 200 in a first direction (e.g., counterclockwise when viewed from above) about central axis 411 of drinking opening 410, and such rotation may cause central portion 300 to move down along central axis 411 (e.g., in a direction toward container 600 when closure 100 is attached to container 600). For example, as top portion 400 is rotated in the first direction, central portion 300 may move from the open position shown in FIGS. 1, 3, and 5 to the closed position shown in FIGS. 2, 4, and 6.

When central portion 300 moves down central axis 411, drinking opening 410 may be unsealed and top portion 400 may be in a second configuration (e.g., an open configuration, as shown in FIGS. 2, 4, and 6) in which fluid may flow (e.g., along fluid path 700) through closure 100 to and through drinking opening 410. Closure 100 may be resealed by rotating top portion 400 relative to base portion 200 about central axis 411 in a second direction opposite the first direction (e.g., clockwise when viewed from above), and such rotation may cause central portion 300 to move up along central axis 411 to seal closure 100.

FIGS. 1-7 show various views of an exemplary closure 100. FIGS. 1, 3, and 5 show closure 100 when drinking opening 410 is sealed (i.e., a closed configuration of closure 100, in which central portion 300 is in a closed position). FIGS. 2, 4, and 6 show closure 100 when drinking opening 410 is not sealed (i.e., an open configuration of closure 100, in which central portion 300 is in an open position). FIG. 7 is an exploded view of closure 100, showing base portion 200, central portion 300, and top portion 400 exploded.

As shown, for example, in FIGS. 3-6, closure 100 includes base portion 200 that may be coupled to a container (e.g., container 600). In some embodiments, base portion 200 includes internal threads 210 that extend circumferentially around the interior of base portion 200. Internal threads 210 may engage with corresponding threads on container 600. In some embodiments coupling internal threads 210 to threads of container 600 secures base portion 200 such that when top portion 400 is rotated relative to base portion 200, base portion 200 does not rotate relative to container 600.

As shown, for example, in FIGS. 3 and 4, base portion 200 includes engagement portion 220. In some embodiments, base portion 200 includes two or more engagement portions 220. For example, as shown in FIGS. 5-7, closure 100 may include two opposing engagement portions 220, positioned oppositely from each other across axis 411. Engagement portions 220 may engage with corresponding translational engagement portions 320 of central portion 300 to restrict rotational movement of central portion 300 relative to base portion 200, but to allow vertical movement of central portion 300 relative to base portion 200 and relative to top portion 400.

For example, engagement portions 220 may define a vertically-oriented groove 221 (i.e., oriented in the same direction as central axis 411) that receives a projection 321 of translational engagement portion 320 of central portion 300. Alternatively, translational engagement portion(s) 320 may define a groove and engagement portion(s) may define a corresponding projection received in the groove.

As shown, for example, in FIGS. 3, 4, and 7, base portion 200 includes engagement portion 240 that engages with a corresponding engagement portion 450 of top portion 400. In some embodiments, engagement portion 240 is engaged with engagement portion 450 such that top portion 400 is not separable from base portion 200. In some embodiments, engagement portion 240 is engaged with engagement portion 450 such that top portion 400 is rotatable relative to base portion 200 (e.g., about central axis 411) but is not vertically movable relative to base portion 200 (e.g., along central axis 411). This allows a user to easily rotate top portion 400 without unscrewing base portion 200 from the container, and the rotation of top portion 400 initiates the movement of central portion 300 along central axis 411.

In some embodiments, base portion 200 includes an opening 230 that aligns with drinking opening 410 of top portion 400. When assembled together, central portion 300 may extend through opening 230.

Central portion 300 of closure 100 may include plug 310, one or more translational engagement portions 320 (which may include one or more outward facing projections 321), one or more rotational engagement portions 330, and one or more fluid openings 340. In some embodiments, central portion 300 includes four fluid openings 340. Translational engagement portion(s) 320 may engage with corresponding engagement portion(s) 220 on base portion 200, as described above. Rotational engagement portions 330 may engage with corresponding engagement portions 420 on top portion 400, as described in more detail below.

As shown in FIG. 7, translational engagement portions 320 may include outward facing projections 321. In some embodiments, outward facing projections 321 couple to the vertically-oriented groove 221 to secure central portion 300 within base portion 200, and projecting stops 222 prevent the central portion from being removed. When the closure is opened (i.e., in the second configuration), the threads (e.g., rotational engagement portions 330) on central portion 300 may not be engaged with the threads (e.g., corresponding engagement portions 420) on top portion 400. Accordingly, when the closure is opened, central portion 300 is held in place only by projecting stops 222. This configuration allows for central portion 300 to be removed as described in more detail below.

In some embodiments, central portion 300 includes rotational engagement portion 330 engage with a corresponding engagement portion 420 of top portion 400. In some embodiments, rotational engagement portion 330 is one or more threads that couple to engagement portion 420, which may also be one or more threads. For example, FIGS. 3-4 show rotational engagement portion 330 engage with engagement portion 420. FIG. 7 shows an exploded view of closure 100, which includes rotational engagement portion 330 (e.g., external threads) on an outer side of central portion 300 and engagement portion 420 (e.g., internal threads) on an internal side of drinking opening 410. In some embodiments, rotational engagement portion 330 engages with engagement portion 420 by a screw fit, as shown in FIGS. 3 and 4.

Squeezing each of the translational engagement portions 320 (which are resilient) toward the central axis allows translational engagement portions 320 to bypass inwardly-projecting stops 222 at the ends of engagement portions 220, and then pulling down along the central axis will release central portion 300 from both base portion 200 and top portion 400. In some embodiments, central portion 300 can be removed only when top portion 400 is in the second configuration (i.e., drinking opening 410 is unsealed). For example, in some embodiments, rotational engagement portion 330 may disengage from corresponding engagement portion 420 when top portion 400 is in the second configuration. Then squeezing each of the translational engagement portions as described above will remove central portion 300 by allowing projections 321 to bypass stops 222. Once separated, plug 310 can be separated from central portion 300. With these parts separated, a user can easily clean all of the components of closure 100. To reassemble closure 100, the user need only reattach plug 310 (if it has been removed) and reinsert central portion 300 by pushing up along central axis 411 until translational engagement portions 320 engage with engagement portions 220.

In some embodiments, central portion 300 includes plug 310. Plug 310 may be integrally formed with or permanently affixed to central portion 300. If plug 310 is integrally formed with central portion 300, plug 310 may be made of the same material (e.g., plastic) as central portion 300. If plug 310 is permanently affixed to or removable from central portion 300, plug 310 may be made of a different material than the material that makes up central portion 300. In some embodiments, plug 310 is made of a resilient material (e.g., silicone). The use of a resilient material allows for flange 430 to press into and deform plug 310 to form the seal.

In some embodiments, plug 310 is removably attached to central portion 300. Plug 310 may stretch to fit over flange 350. For example, as shown in FIGS. 3 and 4, plug 310 is secured to central portion 300 by stretching over flange 350. In some embodiments, plug 310 is made of a material with sufficient elasticity to compress to form a water tight seal when the drinking opening 410 is sealed.

Top portion 400 of closure 100 may include drinking opening 410 through which fluid may flow, depending on the position of central portion 300. In some embodiments, drinking opening 410 has a diameter between about 5 millimeters and about 50 millimeters (e.g., between about 10 millimeters and about 40 millimeters, between about 15 millimeters and about 35 millimeters, or between about 20 millimeters and about 30 millimeters). In some embodiments, drinking opening 410 has a diameter of about 25 millimeters. In some embodiments, drinking opening 410 has a diameter of about 30 millimeters. For example, drinking opening 410 may have a diameter that is about the same size as a standard opening for a single-use beverage container (e.g., a sports drink bottle or a soda bottle).

In some embodiments, closure 100 includes engagement portion 450 (e.g., an inward projection) that couples to a corresponding engagement portion 240 (e.g., on base portion 200). In some embodiments, coupling top portion 400 to base portion 200 using engagement portion 450 and engagement portion 240 allows top portion 400 to rotate about a central axis of the closure without moving along the central axis. In some embodiments, top portion 400 is rotatable in the counter-clockwise direction when viewed from above. In some embodiments, top portion 400 is rotatable in the clockwise direction when viewed from above. In some embodiments, top portion 400 is rotatable in both the counter-clockwise direction and the clockwise direction. Top portion 400 may be rotatable about the central axis between 0 degrees and 360 degrees (e.g. between 0 degrees and about 270 degrees, between 0 degrees and about 180 degrees, between 0 degrees and about 90 degrees). In some embodiments, top portion 400 is rotatable between 0 degrees and 180 degrees. The rotation of top portion 400 may be limited by one or more rotation stops on base portion 200.

In some embodiments, top portion 400 of closure 100 includes an engagement portion 420 (e.g., internal thread) that couples to a corresponding rotational engagement portion 330 on central portion 300. In some embodiments, top portion 400 includes one or more grip portions 440 that aid a user in gripping top portion 400 while turning top portion 400 about central axis 411 relative to base portion 200 and central portion 300.

In some embodiments, top portion 400 includes flange 430. In some embodiments, flange 430 extends circumferentially around drinking opening 410 and projects inwardly from the drinking opening 410. In some embodiments, flange 430 has a diameter between about 5 millimeters and about 50 millimeters (e.g., between about 10 millimeters and about 40 millimeters, between about 15 millimeters and about 35 millimeters, or between about 20 millimeters and about 30 millimeters). In some embodiments, flange 430 has a diameter of about 25 millimeters. In some embodiments, drinking opening 410 is defined by flange 430. In some embodiments, flange 430 has a diameter that is smaller than the diameter of plug 310. For example, flange 430 may have a diameter that is between 80% and 90% (e.g., between 82% and 88% or between 84 and 86%) of the diameter of plug 310. In some embodiments, flange 430 may have a diameter that it at least 2 millimeters (e.g., at least 3 millimeters or at least 4 millimeters) smaller than a diameter of the plug 310.

Closure 100 may be configured to couple to container 600 (e.g., a beverage container) with sidewall 610. In some embodiments, container 600 may include a rigid, inflexible sidewall 610. For example, container 600 may be a stainless steel container or a hard plastic container that contains free flowing liquids that can be poured or sipped through closure 100 when closure 100 is opened. In some embodiments, container 600 may include a flexible sidewall 610. For example, container 600 may be a squeeze bottle that allows the container to hold and dispense viscous fluids through closure 100. Container 600 have a volume between 500 milliliters to 1500 milliliters (e.g., between 600 milliliters to 1250 milliliters or 750 milliliters to 1000 milliliters). In some embodiments, the container 600 has a volume of about 750 milliliters.

Closure 100 may include attachment 500 coupled to base portion 200 that improves portability of closure 100 when coupled to container 600. Attachment 500 may be a carabiner, a loop, a hook, or a handle. In some embodiments, attachment 500 is hinged. In some embodiments, attachment 500 is removably attached to base portion 200.

Base portion 200 may be coupled to top portion 400 such that top portion 400 rotates freely about central axis 411. In some embodiments, base portion 200 includes engagement portion 240 that couples to engagement portion 450 of top portion 400. This coupling may allow top portion to rotate freely about central axis 411. Top portion 400 may further include a rotation stop that limits rotation of top portion 400 about the central axis, for example

Opening 230 may be in fluid communication with drinking opening 410. In some embodiments, opening 230 aligns with drinking opening 410 to form a cylindrical shaped opening. When the base portion 200 is coupled to top portion 400, central portion 300 may be inserted into the cylindrical shaped opening formed by opening 230 and drinking opening 410. In some embodiments, central portion 300 is inserted from the bottom of the combined base portion 200 and top portion 400.
